Blue Lagoon - Iceland 

Situated near Reykjavik in Iceland, the Blue Lagoon is a unique geothermal spa that has been open to the public for bathing since 1992. The waters are rich  in minerals like silica and sulfur, and have been known to cure skin irritations. The geothermal waters originate 2,000m below the surface of the lagoon.

The colour of the lake depends upon the mineral make up of the water. The blue appearance is the result of silica in the water, and they way the silica reflects in the sunlight. In summer, the lagoon can appear green, due to the algae’s reaction to the sun. But if you pour the water from the lagoon into a transparent cup, you will see that the water is actually milky white! 

The Blue Lagoon geothermal spa is one of the most visited attractions in Iceland. The steamy waters are part of a lava formation. The warm waters are rich in minerals like silica and sulphur and bathing in the Blue Lagoon is reputed to help some people suffering from skin diseases. The water temperature in the bathing and swimming area of the lagoon averages 37-39 °C.

The Lagoon is man-made, having formed in 1976 from the waste water of a recently built geothermal power plant. In 1981 people started bathing in it after the discovery of its healing powers for psoriasis, and in 1992 the Blue Lagoon company was established and the bathing facility was opened for the public. The Blue Lagoon also operates a research and development facility to help find cures for other skin ailments using the mineral-rich water. The water temperature in the bathing and swimming area of the lagoon averages 37–39 °C.  

“I was on tour with the Foo Fighters in 2003 when we made a stop in Iceland. We had heard about the blue lagoon geothermal spa and were all really excited to check it out.

I decided to wade in with my widelux to capture the huge expanse of blue water. Soon after this, the band descended on a small town on the coast for dinner, where we could hear a band rehearsing in a garage down the street. Turned out to be a few teenagers, and before you know it the band joined these kids playing in the garage…of course, Dave asked the boys to open up for the Foo Fighters the following night in Reykjavik” - Danny Clinch
